"WIRE-TIE-FORMING MACHINE.

Specification of Letters Patent.

Patented Nov. so, 1915.

To all whom it may concern:

Be it known that I, ADELMER M. Barns, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in YVire-TieForming Machines, of which the following is a specification.

My invention relates to improvements in means for forming wire ties and the like having particular reference to grouping the successive forming wire ties in a belt or band arrangement.

It is illustrated more or less diagrammatically in the accompanying drawing, where- 111-- Figure l is a front elevation of a machine with parts omitted and parts in section; Fig. 2 is a section along the line 22 of Fig. 1; Fig. 3 is a section along the line 3-3 of Fig. 1; and Fig. i is a section along the line 4L of Fig. 3; Fig. 5 is-a detail vertical section of the mandrel shown in modified form; and Fig. 6 is a plan view of the fin ished tie.

Like parts are indicated by like letters throughout the several figures. 1

A is a main frame upon which are mounted two bracket arms A, A These bracket arms contain each a vertically disposed rotatable sleeve A A having gears A mounted thereon. These gears are in engagement with a rack A which may be reciprocated by any desirable means not here illustrated to rotate the sleeves.

A A are forming mandrels held against rotation but slidable within the sleeves A is a rock arm mounted on the rock shaft A which may be rocked by any suitaole means not here shown to reciprocate 'the forming mandrels at the proper time to Withdraw them from the wire tie and cause it to drop from the mandrel by pressing it against the end of the sleeves A A A ,'A are twisting fingers mounted on the sleeves A A and adapted to engage the wire A and twist it about the mandrel as they rotate.

B is a twisting mandrel through which the wire A projects and is adapted to'be rotated by the gear B driven by 211i) suitable means not shown to complete the tie by twisting its ends a round the wire thus forniing eyes at these ends. I t will be noted that the finger A moves from the position shown in Fig. 3 in full lines to that shown in dotted lines to bend the wire shown in dotted lines, whereupon the mandrel B rotates to bend the free end up around the wire. The rotation of the fingers A, A is substantially. through an angle of 270, thus for 90 the forming mandrel is not quite covered by this finger. v

C is a slot or groove in the end of the mandrel A extending upwardly from the end for a short distance. Through this slot is looped a cord C which comes from the reel (1 and passes through the eyelet C3 and down over the roller 0* passing through" and'holdiug together the adjacent ties C as they are fed from the machine. These ties are thus held by the cord in a belt which is wound around the roller. It will be noted that each eye is formed about the string or cord so that as the ties are discharged each tie is held in position and cannot escape.

In the modified form shown in Fig. 5 the outside wall of the slot G is closed up to form. an aperture or passage through or within the mandrel adjacent its forming end through which the string may be made to pass. v

It will be evident that while I have shown in my drawings an operative device, still many changes might be made both in size, shape and arrangement of parts without departing from thespirit of my invention, and I wish, therefore, that my drawings be regarded as in a sense diagrammatic.

It will be understood that these wire ties are those looped wire ties which are so common when applied as closures for sacks and the like. It will be. understood that in operation they are used by atool which enters, the loops at either end of the tie and draws the tie around the bag or other. object to be tied. The tool then twists the ends oi the tie together, thus forming a centrally constricted loop leaving the two eyes bearing ends projecting outwardly as keys, whereby an operator who wishes to unload or release an object may turn or twist in the opposite dire tion to get the desired releasing result.

T have used the term a forming zone. It is understood that this zone means that small area about each of the two vertical mandrels where the forming takes place. it is an area wherein considerable pressure is applied to the mandrel by the wire and finger, and in that zone or area the twisting, forinlng or looping of the tie takes place.

I claim 1 In a wire tie forming machine, a mandrel, slolted to permit passage of a cord therethrough, and means, for forming'a Wire tie about said mandrel to inclose the cord.

2. In wire tie forming machine, a mandrel, slotted to permit passage of a cord therethrough, means for forming a Wire tie about saia mandrel to inc/lose the cord, a frame, and means for winding up successive ties in a belt thereupon.

3. In a wire tie forming machine, a mandrel, slotted to permit passage of a cord therethrough, a guide for the cord, and

-means for forming a Wire tie about said mandrel to inclose the cord.

4. In a Wire tie forming machine, a. mandrel, slotted to permit passage of a cord therethrough, means for forming a wire tie about said mandrel to inclose the cord, and means for discharging successive ties from the mandrel along the cord.

5. In a wire tie forming machine, a mandrel apertured adjacent its forming end, to permit passage of a cord therethrough, and means for forming a Wire tie around the cord.

6. In a Wire tie forming machine, a mandrel apertured to permit passage of a cord therethrough, a forming zone about said mandrel, said aperture being closed at the forming zone but open on bothsides of it.

In testimony whereof, I affixmy signature in the presence of two Witnesses this th day of August 1914.
